Tempo SC Ultra has a residual of 30 days outdoors and 90 days indoors. It is labeled for flies as well. You will use between 8-16 ml per gallon of water. If you are looking for a 90 day residual indoors and outdoors, we would recommend using Suspend Polyzone. This has an additional polymer in it that protects the product from the outdoor elements.
